  • Publication number: 20080037475
    Abstract: The present invention provides a data rate controller system for determining the coder used, and hence the data rate, for a plurality of channels in an associated network. Each channel provides statistical information about an associated signal to a central controller (or call/resource manager). The controller considers the information and sends control instructions to each channel for selecting an appropriate coder and/or data rate. The statistical information might include lost-frame rate, jitter, call event discrimination, and system resource utilization. By considering each channel from a centralized standpoint, the network can be optimized according to network capabilities and channel resource capabilities. A profile might also be used where each channel autonomously chooses a coder based upon background noise derived from the source signal.

    Abstract: Mobile wireless device(s) roam within and between premises and a vehicle or other mobile platform and interface to wireless local area networks within the premises or vehicle. When using the intra-vehicular network, a communication relay within the vehicle routes communications from the wireless device to a wide area wireless network such as cellular network or satellite network. This allows the power consumption of the mobile wireless device to be greatly reduced as the mobile device need only communicate with the local intra-vehicular WLAN. The vehicle acts as the power supply for the relay. When the coverage area of the intra-vehicular WLAN overlaps that of another WLAN, seamless handoff allows continuous data or voice connectivity between the overlapping wireless networks.

    Abstract: A base station (103) assigns a set of mobile stations (101) to a group wherein the group will share a set of radio resources (770). A shared control channel information element (501) is sent to the group of mobile stations (101) and provides a bitmap having fields for group ordering (511), resource allocations (530), continuation resources (540) for HARQ, and an ordering pattern (513). If a mobile station requires retransmission it will access the resources indicated by the continuation resources field (54) in order to receive data. The HARQ blocks may be assigned to a mobile station based upon an index (601) which may correspond to the mobile station vocoder rate. Further, HARQ subgroups may be defined to associate subgroups of mobile stations with specific HARQ transmission opportunities on the super-frame and allocated by a rotating bitmap.

  • Publication number: 20080037497
    Abstract: A method for selecting a subset of sites within a set of candidate sites for activating one or more radio stations of a telecommunications network includes building an initial solution of a subset of sites starting from a network configuration having the whole set of active candidate sites; and optimising the initial solution for activating “inactive” sites and/or deactivating “active” sites, in order to minimise a predetermined cost function for the solution. The steps of building and optimising the initial solution are adapted to define both solutions that have a geographic coverage area that is greater than a predefined minimum coverage area and to manage an amount of traffic that is greater than a predefined minimum expected traffic value. A processing system and a processing program or group of programs can be executed by the system when pre-arranged for performing the above method.
